EL5420T

12MHz Rail-to-Rail Input-Output

Operational Amplifier

The EL5420T is a low power, high voltage rail-to-rail

input-output amplifier. The EL5420T contains four amplifiers.

Each amplifier exhibits beyond the rail input capability,

rail-to-rail output capability and is unity gain stable.

The maximum operating voltage range is from 4.5V to 19V. It

can be configured for single or dual supply operation, and

typically consumes only 500µA per amplifier. The EL5420T

has an output short circuit capability of ±200mA and a

continuous output current capability of ±70mA.

The EL5420T features a slew rate of 12V/µs. Also, the

device provides common mode input capability beyond the

supply rails, rail-to-rail output capability, and a bandwidth of

12MHz (-3dB). This enables the amplifiers to offer maximum

dynamic range at any supply voltage. These features make

the EL5420T an ideal amplifier solution for use in TFT-LCD

filtering and signal conditioning applications. Other

applications include battery power and portable devices,

especially where low power consumption is important.

The EL5420T is available in a 14 Ld TSSOP package,

14 Ld SOIC package, and a space saving thermally

enhanced 16 Ld QFN package. All feature a standard

operational amplifier pin out. The devices operate over an

ambient temperature range of -40°C to +85°C.
